2 Claims. (01. 196-46) 11 This invention relatesto oil purifiers, and more particularly to a machine for treating the crude oil as it is pumped from the wells, therebybreaking up and precipitating the waste,.sludge, im-

purities, and other foreign matter which possesses 3 disagreeable odors, and materially interferes with the cracking and final refining of the product.

7 One of the prime objects of this invention is to design a machine providedwith means for agitating theoil and treating'it with absorbents for the purpose of .deodorizing and purification. Another object is to provide a machine including a plurality of disks provided with inclined members thereon, and openings in the disk to permit the passage of the precipitated sludge and foreign matters asthe machine is in operation.

A further object is to design a machine of simple, practical, and substantial construction, which i can be readily opened and disassembled for cleaning and/or repair, and which in operation, requires a minimum of supervision and attention.

Still a further object is to provide a plurality of outlets at certain predetermined points for draining off the treated oil removal of sludge and other impurities.

A further object still is to provide a machine of the character described and in which the disks, shaft, and agitating means can be inserted and/or removed as a unit, thereby simplifying the cleaning, repair and/or replacement of parts and the cleaning of the machine proper.

With the above and other objects in view, the

present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out inthe appended claims, it being understood that changes may be made in the form, size, proportion and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention. i

In the drawings:

Fig. 1 is a side elevational view showing our improved machine Fig. 2 is a top plan view thereof;

Fig. 3 is an enlarged detail plan showing one of the disks with the agitating means mounted thereon;

Fig. 4 is an edge view thereof; and, i

Fig. 5 is a fragmentary sectional view of the disk taken on the line 4-4 of Fig. 4.

. Referring now more particularly to the draw ings in which we have shown the preferred embodiment of our invention, the numeral 8 indicates the casing or shell of the machine, thisis and also to permit easy preferably cylindricalin shape and can be either cast or welded as desired, the bottom being open and a conical shaped section 9 forms a closure for the open end, and issecured thereto by means of bolts I 0, a gasket I I being interposed and forms a leakproof joint as usual. Openings [2 are provided in said conical section 9 to permit the easy and quick removal of sludge or other foreignmatter that may collect in the bottom, and conventional gates G form a closure for .these ,ODenings and are easily and quickly operable. l l

A cover member l4 forms a closure for the top of the shell and a bearing I5 is provided in the upper end as shown, an end bearing l6 being mounted in the bottom section 9, and a centrally disposed vertical-shaft I1 is journaled in said bearings, the upper end projecting beyond the cover, and a pulley I8 is mounted thereon for transmitting power from any suitable source of supply, or an electric motor may be located on i the cover to provide an individual drive unitif desired.

A plurality of disk members I 9 are mounted on the shaft I! in spaced apart relation, each disk being formed with a hub 20 to facilitate attachment to the shaft, and a plurality of radially disposed agitating members 2! are provided on the face of each disk, and are welded or otherwise secured in position, openings 22 being provided as shown, and these openings are of predetermined size to permit limited circulation of the oil and precipitation of the sludge as the machine is in 7 operation.

Inlet pipes, lines 23 and 24 respectively are provided as shown, and open into the shell at a point directly adjacent the lower end thereof, the pipe 23 being connected to any suitable source 7 of crude oil supply, and the pipe 24 is connected to a source of water supply. Valves 25 are provided in the lines 23 and 24 for controlling the admission of oil and water to the shell. Similar pipes 26 and 21 respectively are provided adjacent the upper end of the shell, and valves 28 are provided thereon as usual, the pipe 21 opening into the shell at a point below the pipe 26, so that water may be drained as desired, the pipe 21leading to a suitable tank or other receptacle (not shown), so that as the oil is treated, it can be discharged from th shell through the pipe 21 and into a tank as above described. As the oil is treated, the purified, more volatile oil rises to the top, Whereas the sludge, impurities, and other foreign matter precipitates and collects in the conical bottom of the shell and is removed through the gates G when desired.

In practice, the valves 25 are opened to admit crude oil and Water to the machine through the been in operation the required period of time, the

length of time being dependant on the oil being treated. After the sludge bed has builtup in the conical part of the shell, the gates-G-arezopened to permit the removal of noxious sludge and v 1. A crude oil purifier of the class described comprising a cylindrical shell having a conicalshaped detachable bottom section, a vertically disposed driven shaft journaled in said shell and in the conical-shaped bottom section, disks mounted on said shaft in spaced relation and provided with a plurality of radially disposed upwardly inclined agitator vanes secured on the face thereof, l-intake pipes opening into ,the lower end of the shell, outlet pipes opening into the upper end of the shell and vertically spaced with relation to each other, openings in the bottom section of the shell, and quickly operable gates forming-closures for said openings.

2. A--crude oil purifier of the character described comprising a closed shell and including foreign matter, thereby eliminating the odors,

after which the gates are again closed for further operation. 7

For the purpose of aiding the purification and deodorization of the oil as it is treated in' the' ma- 'chine,-we' add certain ingredients, etc. to the crude in the machine, or to the source of crude flow, 'this however, forms the subject matter of a separate application to be filed by us 'and forms no part of the presentinvention.

"From the foregoing description, itlwill be obvious thatwe have perfected a"-very simplepractical, and inexpensive machine for treatingcrude "oilas-it' flows from the wells. What we claim is:

a detachable conical shaped bottom, a vertically disposed, driven shaft journaled in said shell and bottom section, disk members mounted on said shaft in vertically spaced relation and provided with openings 10f predetermined size in the-face zthereof, radially disposed, Verticallyiinclineiagitator vanes :on the face ofeachdisk, intake @pipes opening :intoithe lower section of the shell, outlet :openings adjacent the upperend o'f'the shell and vertically spaced With relation to each other,

sludge tdischarge openings .in the conical bottom section,;and quickly operableagates forming a closure forsaid discharge :openings.
